The strength of legs of a jack-up drilling platform serviced in Bohai Sea is evaluated and the ice-induced fatigue damage of the platform leg under different ice parameter was determined.

The strength of a jack-up platform serviced in Bohai Sea is checked by using the method proposed in this paper,the ice-induced fatigue damage of the platform leg under different ice parameter is calculated.

The detailed process of fine assessment on the time-field of ice-induced fatigue on the offshore platform is presented in order to evaluate the safety reliability of offshore platform in the ice region within the service period.

The propagation rules of hot fatigue of H13 used for die casting dies were studiedthrough simulating the work conditions of die casting dies.

Study of failure mode and failure mechanisms on thermal fatigue of plasma sprayed thermal barrier coatings;

Changes of morphology and composition of carbides in H13 steel after thermal fatigue;

Effect of heat treatment conditions on the thermal fatigue properties of WC/steel composites;

CoCrMoSi coating was deposited on CrZrCu with HVOF,and its cold-hot fatigue and war resistance were studied,analyzed and compared with NiCo plated coating widely applied in metallurgy industry.

Co based alloy coating was deposited on the narrow side CrZrCu plate of the slab continuous caster with HVOF and the cold-hot fatigue was compared with Co-Ni plating coating.
